“…Recovery and utilization of wasted components of main raw materials are the key challenge for various industries. Some recent developments in respect of value-added products from underutilized waste are providing the solution toward green and clean technologies. − The concept of waste management has been applied over the years in all the commercial activities including pulp and paper mills. The ever-increasing demand of energy and the limited availability of conventional energy sources have fostered pulp and paper industries to develop the integrated production of pulp, paper, and other valuable byproducts such as bioethanol. , Agricultural waste, preferably wheat straw, a major contributor in the pulp and paper sector, which is rich in carbohydrate content, would be an attractive feedstock that can be channelized for the production of bioenergy and various bioproducts in near future. − While processing a raw material for pulp production through different chemical treatments, a major proportion of carbohydrates, predominantly hemicelluloses, are wasted, thereby reducing the pulp yield as well.…”

Cleaner production of sugars and pulp from renewable feedstocks has captured significant scientific attention in the recent past because they can be used for various end applications. In the papermaking industry, a major fraction of hemicellulosic sugars is lost during the pulping. The present study aims at retrieving these hemicellulosic sugars through alkali-, hot-water-, and acid-mediated extraction prior to pulping, which otherwise would have been lost during pulping and washing of pulp. These retrieved sugars can be used as feedstocks for renewable energy and value-added products. Different pretreatments were applied, aided with varying temperature, chemical concentrations, and time. Substantial amounts of total reducing sugars (TRSs) up to 21.98, 13.2, and 15.01% were extracted prior to pulping by acid, alkali, and hot-water pretreatments. Compositions of mono sugars present in the treated liquor were also characterized and confirmed by high-performance liquid chromatography analysis. The morphological changes in the wheat straw after pre-extraction were studied using the field emission gun scanning electron microscopy technique. Pulping of untreated and pretreated wheat straw was carried out at different alkali charges (12, 14, and 16% NaOH). Among all, acid-pretreated straw showed an increase in pulp yield by 10.9% at a 16% alkali charge. Physical strength properties of different pulps were further examined. Alkali- and hot-water-pretreated straw pulp retained 94.26 and 83.16% tensile indices and 92.43 and 87.02% burst indices, respectively. An increase in tear index up to 4.32, 2.01, and 2.30% for alkali-, hot-water-, and acid-pretreated straw pulp was achieved, respectively. Hot-water- and alkali-pretreated wheat straw was observed to be conducive for paper production. The integrated use of wheat straw for extraction of underutilized sugars and pulp production in this way may serve as a key stepping stone for future biorefinery designs in pulp and paper mills.

“…Thus, the integrated management of affordable waste into usable finished products is relevant today. Many enterprises have as their main objective the introduction into production of waste-free production technology, or the development and implementation of technology that allows the use of waste from related industries (Gupta et al, 2020). Currently, according to the official data of the Food and Agriculture Organization of the Unated Nations, 1.5 billion hectares are used for growing of agricultural crops (Food and Agriculture Organization of the United Nations, 2023).…”

The pulp and paper industry is at its peak due to the annual growth in demand for paper products which includes packaging board, hygienic paper products, printing papers and the list is endless. To date, the main source of raw materials for pulp and paper production is wood. However, its use and the use of standard flow charts in pulp and paper production creates environmental problems. For example, deforestation to obtain raw materials leads to a disruption of biogeocenoses, and technology using alkalis and acids are sources of toxic wastewater that pollute the hydrosphere and lithosphere. In order to avoid the above environmental problems, other options for sustainable sources of raw materials can be considered, such as agricultural waste - straw. By its natural origin, straw is a non-woody plant, which will significantly simplify the flow chart of pulp and paper production, on the one hand, and on the other hand, the use of straw in production will help to reduce the risks of early global warming, since most of the straw is burned in the fields. As far as toxic wastewater emissions are concerned, they can be drastically reduced through the biological degradation of straw lignin to produce pure pulp. Biodegradation of lignin can be produced by widespread wood-destroying fungi due to their ability to synthesize lignin-degrading enzymes. Thus, the use of biological agents in pulp and paper production will make it possible to eliminate the use of caustic acids and alkalis.
